IMPROVEMENT IN HANGERS FOR SHAFTING.

Specification forming part of Letters Patent No. 185,154, dated December 5, 1876; application tiled November 15, 1876.

To all lwhom it may concern:

Beit known that I, JAMEsYocoM, Jr., ofthe city and county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Han gers for Shafting, of which the following is a specification:

My invention relates to that class of hangers in which the bearing or journal-box of the shaft is supported between two movable posts tted to sockets upon the hanger, and adjustable therein by means of set-screws, and is designed to obviate the difficulty which has heretofore existed in obtaining proper bearings for the posts. To this end my improvement consists in providing` a metal bushing or sleeve for each post, said bushings being' either chilled or bored out on their interior surfaces, and placed within and suitably supported in the mold in which the hanger is cast, so that themetal shall be cast around them, the bushings constituting. the bearings within which the posts rest, as hereinafter lmore fully set forth.

In the accompanying drawings, Figure lis an end view, partly in section, of a hanger embodying` my improvement; and Fig. 2, a horizontal section ofthe same at the line :v :v of Fig. l.

My improvement is shown as applied to a hanger, A, the general plan of construction of which is substantially similar to that for which Letters Patent of the United States, numbered 68,826, were granted and issued to me under date oi' September 10,1867. The

bearing or journal-box B is supported between two movable posts, C C, which are adjustable A vertically within sockets a a, by set-screws D D, engaging nuts b b in the sockets.

It will be obvious that by reason of the relative position of the two sockets and the short distance between them, they cannot conveniently be bored out, and I have found, in practice, more or less difficulty in casting the sockets around chills. I dispense with the necessity of boring the hanger after casting,-

aud avoid risk of failure in chilling, by providing a met-al bushing or sleeve, E, for each post, cach bushing being eitherbored out or internally chilled. rlhe bushings E E are placed in proper position in the mold,.and. suitably secured therein, preferably by internal chills, and the metal of the hanger is cast around them, so as to bed and hohl them within their respective sockets.
